Clean Today. Cleaner Tomorrow.®
At Idaho Power, our commitment to safely serving customers and communities with safe, reliable, affordable energy has been the hallmark of our 100-year history. As we continue the next century of service, we are building on that foundation.
100% clean energy by 2045*
In 2019, Idaho Power adopted a goal to achieve 100% clean* energy by 2045 from our generation resources. In setting this aspirational target, we recognized that achieving the goal would require technological advances in clean generation resources and renewable energy integration, as well as a continued focus on energy efficiency and demand response programs. Those technological advancements include items like small modular nuclear reactors, hydrogen-fueled generation, fuel cells, and carbon capture and sequestration, at scale, at reasonable prices, and on commercial timelines. We look forward to the increasing viability of such technologies over the next nineteen years. While we continue to invest in clean energy sources today, our Preferred Portfolio and forecasted energy demand show that we need to invest in natural gas resources in the interim to ensure safe, reliable, and affordable service for our growing customer base. We remain focused on reducing emissions and will be actively monitoring advances in technologies that we can deploy to help move us toward a cleaner energy system. As part of our IRP process, we will continue to model 100% clean energy generation as one of the proposed scenarios and submit it to the Idaho Public Utilities Commission (IPUC).

*We define clean as non-carbon emitting at the point of electricity generation.
Today.
Idaho Power’s largest energy source is clean hydropower. Our energy mix also includes wind, solar, and geothermal long-term purchases.
In 2010, we set an ambitious carbon-reduction goal. We met and exceeded it. See our progress as we’ve continued to challenge ourselves with additional carbon-reduction goals.

Through our energy-efficiency programs, customers saved 143,559 MWh of energy in 2024. That’s enough energy to power about 12,600 average-sized homes for a year.
Energy Mix Comparison
Idaho Power 2025 Energy Mix*

*This energy mix shows the energy we generate from company-owned resources and energy we buy through long-term contracts with wind, solar, biomass, geothermal, and small-scale hydro generators. The overall mix does not represent the energy delivered to customers for two reasons. First, we participate in wholesale energy markets and sell energy both to other utilities and to retail customers. Second, power from some renewable sources comes with a renewable energy credit (REC), which we sell to keep customer prices low.

Tomorrow.

We exited one coal-fired generator in 2019 and another in 2020. Two units were converted from coal to natural gas in 2024. We continue to strategically move away from our remaining coal-fired generation.

The Boardman to Hemingway transmission line will give us access to affordable surplus energy, much of it from clean hydropower. We are procuring materials for this project.

We’re investing in solar power. A large array right here in Idaho is sending us energy at some of the lowest rates in the nation.
Together.
